The effects of La0.7Sr0.3MnO3 (LSMO) and BaZrO3 (BZO) additions on the structural, electrical, and magnetic properties of (Bi, Pb)-2223 superconductors were systematically investigated. Samples with varying concentrations of LSMO and BZO were synthesized via the solid-state reaction method. X-ray diffraction (XRD) analysis confirmed that the Bi-2223 phase was retained after the incorporation of both secondary phases, with only slight changes in lattice parameters and crystallite size. Scanning electron microscopy (SEM) revealed that BZO addition enhanced lattice strain and microstructural homogeneity, whereas LSMO addition introduced structural disorder and weak-link behavior. Magnetization measurements at 65 K demonstrated that BZO addition significantly enhanced the critical current density (𝐽𝑐) and flux pinning force density (𝐹𝑝), with the BZ05 sample exhibiting the highest performance. In contrast, LSMO addition degraded superconducting properties due to increased disorder and reduced grain connectivity. Normalized pinning force analysis indicated that surface pinning is the dominant mechanism across all samples, although additional pinning contribution, depending on the additive material, play a crucial role under high magnetic field. Overall, BZO proved more effective than LSMO in enhancing the superconducting performance of (Bi, Pb)-2223, with the BZ05 composition showing the most promising results.
